Board-to-Wire Power Header for Dense Harness Assemblies
The Molex 430451419 is the 14-circuit, dual-row member of the Micro-Fit 3.0 43045 series — a surface-mount header with a 3.00 mm pitch that mates with the matching receptacle housing for board-to-cable/wire power interconnects. The 8 A per circuit rating at 600 V places this firmly in the power distribution class, not signal-only duty. The locking ramp fastening provides positive retention against vibration-induced disconnection — relevant for automotive, industrial, and telecommunications environments where the harness sees movement.
Position Count and Pitch — Fit Check
At 14 positions across two rows spaced 3.00 mm apart, this header occupies a board footprint that matches the 14-circuit Micro-Fit 3.0 receptacle housing.
